ATTINY25-15MZ

Overview

The ATtiny25-15MZ is an automotive-grade 8-bit AVR microcontroller featuring a 2 KB in-system programmable flash memory, 128 bytes of EEPROM, and 128 bytes of internal SRAM. It operates at speeds up to 15 MHz within the 4.5V to 5.5V voltage range and supports 0 to 8 MHz operation between 2.7V and 5.5V. The device utilizes a 20-pin QFN package and functions across an extended temperature range of -40°C to +125°C.

Feature Summary

• Automotive quality grade verified per AEC-Q100 standards
• Enhanced RISC architecture with single-cycle execution
• Integrated universal serial interface and 10-bit ADC
• Programmable watchdog timer and analog comparator

Applications

• Automotive embedded control systems
• Industrial sensor interfaces
• Consumer electronics requiring high reliability

Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and temperature range for your application. Confirm package compatibility during PCB layout review. Ensure supply chain sources provide authentic components with full traceability documentation to meet automotive quality requirements.

Selection Notes

Select this component when automotive qualification is mandatory. Choose based on the required operating frequency relative to the supply voltage. Consider the 20-pin QFN package constraints for thermal management and physical footprint limitations in dense assemblies.

Part Context

This part belongs to the ATtiny25/45/85 Automotive family manufactured by Microchip Technology. It shares architectural similarities with industrial variants but includes enhanced testing and reliability verification to satisfy strict automotive industry standards for long-term durability and performance consistency.

Replacement Considerations

Direct substitutes include other ATtiny25 variants with matching package and temperature grades. Verify pinout compatibility and ensure the replacement meets the same AEC-Q100 automotive qualification standards.
